A patient has been admitted to the postsurgical nursing unit after surgery. The health care provider has ordered the patient to have an IV of 0.9 sodium chloride. The nurse who is caring for the patient recognizes this as what type of solution?

Isotonic

Hypnotic

Hypotonic

Hypertonic

Answer and Explanation

The Correct Answer is A

A. 0.9% sodium chloride (normal saline) is isotonic, meaning it has the same concentration of solutes as blood plasma. It is used to expand intravascular volume and replace fluids and electrolytes.

B. "Hypnotic" refers to medications that induce sleep and has no relevance to IV solutions. This term does not apply to IV solutions.

C. A hypotonic solution has a lower concentration of solutes compared to normal body fluids. Examples include 0.45% sodium chloride (half-normal saline) or 5% dextrose in water (D5W). 0.9% sodium chloride (normal saline) is not hypotonic; rather, it is isotonic.

D. A hypertonic solution has a higher concentration of solutes compared to normal body fluids. Examples include 3% sodium chloride or 5% dextrose in 0.9% sodium chloride. 0.9% sodium chloride (normal saline) is not hypertonic; rather, it is isotonic.

Correct Answer is ["D","E"]

Explanation

D. Persistent headache can occur with elevated levels of gentamicin, as it may indicate neurotoxicity. Gentamicin can cause neurotoxic effects, including headaches, especially when levels are elevated.

E. Tinnitus (ringing in the ears) is a classic symptom of gentamicin toxicity. Elevated gentamicin levels can lead to ototoxicity, which manifests as tinnitus among other auditory symptoms.

A. Insomnia is not typically associated with elevated levels of gentamicin. Elevated gentamicin levels are not known to cause insomnia.

B. Constipation is not typically associated with elevated levels of gentamicin. Elevated gentamicin levels are not known to cause constipation.

C. Xerostomia (dry mouth) is not typically associated with elevated levels of gentamicin. Elevated gentamicin levels are not known to cause xerostomia.

A. Administer the medication using a filter needle. B. Break the ampule by bending the top to the side. C. Flick the bottom of the ampule several times. D. Withdraw medication from the center of the ampule. E. None F. None

Correct Answer is A

Explanation

A. Using a filter needle is indeed a recommended practice when withdrawing medication from an ampule. This is because filter needles are designed to prevent glass particles from being drawn into the syringe after breaking the ampule.

B. Ampules should not be bent to open them. The proper method involves using a gauze or an ampule opener to snap the neck of the ampule away from the body. Bending the ampule can lead to shards of glass, risking injury to the nurse or contamination of the medication.

C. The ampule should be tapped gently to ensure all medication is in the lower portion before opening.

D. Withdrawing medication from the center of the ampule is the correct action because it ensures that the needle does not touch the broken glass edges, which could contaminate the medication or dull the needle.
